(NEW YORK) -- Hurricane Francine strengthened on Tuesday into a Category 1 storm, with winds reaching 75 mph, as it churned in the Gulf of Mexico. The storm is expected to make landfall Wednesday afternoon or early evening in Louisiana, southwest of New Orleans.

Here's how the news is developing:

Weather warnings for Gulf Coast states

A raft of warnings was issued for cities in Louisiana, Mississippi and Alabama ahead of Hurricane Francine’s expected landfall on Wednesday afternoon.

A hurricane watch was issued for New Orleans, with hurricane warnings for Morgan City and Houma on Louisiana’s Gulf Coast.

Tropical storm warnings are in place further east, covering cities including Biloxi, Mississippi, and Mobile, Alabama.

Storm surge warnings were announced for both Biloxi -- where water may rise up to 5 feet -- and Mobile, where water levels may rise by up to 4 feet.

Francine is expected to make landfall as either a high-end Category 1 or low-end Category 2 hurricane, with winds between 90 and 100 mph, the National Hurricane Center said. The Category 2 classification begins with winds of 96 mph.

Landfall may bring tornadoes in areas around New Orleans, Biloxi, Mobile and Pensacola, Florida.

Heavy rain may cause flash flooding from New Orleans all the way up to Jackson, Mississippi through to Wednesday night. As the storm moves into Mississippi on Thursday, it is forecast to produce flash flooding and gusty winds.

Francine is expected to stall through Thursday night into Friday morning, bringing heavy rain to Memphis, Nashville and Paducah, Kentucky.

Francine 295 miles from Louisiana coast

Hurricane Francine is expected to make landfall southwest of New Orleans as a Category 1 hurricane on Wednesday afternoon.

As of early Wednesday, Francine was 295 miles southwest of Morgan City, Louisiana, heading northeast at 10 mph.

Data collected by Air Force Reserve Hurricane Hunter aircraft indicated that the storm strengthened in the early hours of Wednesday, with maximum sustained winds close to 85 mph -- up from 75 mph on Tuesday night.

New Orleans under Hurricane Watch

Emergency officials in New Orleans, Louisiana, warned residents on Tuesday that they should be prepared to shelter in place as Hurricane Francine approached landfall.

A Tropical Storm Warning and Hurricane Watch were issued for areas along the southern Louisiana coast, including New Orleans. A Flood Watch was also issued in Orleans Parish through Thursday morning, the city said.

Mayor LaToya Cantrell signed an emergency proclamation.

"The storm track has shifted more towards the east, which has the potential to worsen impacts for the city, but the storm remains disorganized," the city said in a statement.
